Wendell, I can tell you from personal experience, if there is even the
slightest air leak in the pick up tube or attachment to the engine, the
sucker will just suck air and won't pull oil up (at least at cranking
speeds). A risky way is sometimes starting the engine will provide enough
suction to get things started - but, naturally be prepared to shut it down
immediately if oil pressure does not come up. If you do and it does that
points to an air leak in my opinion. In my book Halomar is OK for the
coolant "O" rings as it more or less just holds them in place and does not
do much in the way of sealing. I always use Ultragray or similar for oil
pan but only use the gasket for the pickup mount.

Subject: [FlyRotary] Re: Oil Flow
Couldn't get oil flow in the engine the other day when trying to fill oil
line to oil cooler and see if oil flowed to the filter. Had used gasket
and
Halomar when assembling pick-up tube to engine, still no flow. Can't see
why
it will not prime. Pulled oil line off and pumped oil into hole to prime
the
pump since it had set for a long time since engine assembly; it spit out
the
oil put in there showing that the pump would work but still didn't suck,
rather it does 'suck'. Should I have used Ultragray instead of the
Halomar?
Any suggestions?
Will put a 3/8" extender on pick-up tube after oil flow is confirmed with
stock set-up (using sandwich mount 1/2" thick like CC mount).
